TUBE-MACfiINE.

To all whom "it may concern:

Be it known that L'JERVIS R. HARBEOK, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Tube-Machine, of which the following is a specification.

This invention relates to machines-for forming tubes from fibrous material by concentrically winding the same upon a mandrel until the desired thickness is attained,

and the object of these improvements is to provide a machine of this type with a plurality of winding mandrels so that the production-of tubes shall be'rapid, continuous and economical.

This invention consists in a pair of longitudinally slidable mandrels rotatably mounted in fixed bearings, each mandrel being adapted to wind up the tube material while the other is discharging.

It further consists in novel constantly running feeding means for the tube material, whereby the same is fed toward the winding mechanism at a constant speed equal to the winding speed of the winding mechanism.

It further consists in novel guiding mechanism whereby the tube material is conveyed to each of a plurality of mandrels alternately.

It further consists, in combination with the guiding mechanism, of shearing mechanism so mounted and positioned that the tube material for one mandrel will be severed before the guide changes position to direct the material to the other'mandrel.

In tube Winding machines, it has long been recognized that the starting and stopping of heavy rolls of tube material is objectionable, and that consequently it is most desirable to have'a winding mechanism so constructed that the tube material will be consumed thereby at a constant rate. To accomplish this, two constantly running mandrels have been provided, each of which employs one half of its time for winding up the tubes, and the other half in discharging the tubes. winding is constantly carried on, and the feeding mechanism may run at a constant rate.

In the accompanying drawings, Figure l I is a'view of the right side and Fig. 2 of the s ecmmaa of Letters Patent. Application flied July a, 1908. Serial No. 441,740.

In this machine therefore, tube- Patented June 13, 1911 is a plan. Fig. 5 is a front view, the casing being broken away on the line EF of Fig. 4:. Figs. 6 to 13 inclusive are details of various parts on larger scales, Fig. 8 being'a cross section on the line CD of Fi 5, and Fig. 11' a cross section on the line H of Fig. 10.

Similar reference characters refer to like parts throughout the several views.-

In this machine a table or base 1 is supported by sides 2,3, 4, and 5, which together 7 form a casing, all resting on a foundation which separately may carry some of the bearings of the driving mechanism. On the table are the bearingsfi for the hubs 7 of the sprocket wheels 8. Secured to plate 1 are the standards 9 which support the suction pipes 10. The wheels 8 (Figs. 10 and 11) are bored and slotted to form teeth Which enter grooves in the longitudinally slidable tube mandrels 11, which are hollow and provided with a longitudinal row of suction holes 12. A collar 13 is secured to the outer end of each mandrel, which collars are provided with circumferential grooves to receive the rings 14 which are provided with pins 15.

Upwardly projecting brackets 17 carry pins 18,- on which are pivoted the levers 19, in the outer ends of which are slots 20 in which the pins 15 engage. The mandrels are slid longitudinally by means of these levers, in the bore of the hubs 7 and' on the pipes 10,

the bores of the mandrels forming air tight joints withvthese pipes. The teeth in the bores of thehubs not only serveto drive the mandrels for winding purposes, but they also serve to remove the tubes from the mandrels. Brackets 22 are secured to the plate 1 and carry cone shaped lugs 21 adapted to form supports for the inner ends of the mandrels during the time of winding, as shown in Fig. 10.

Mounted in the casing is a main shaft 23 to which are secured two bevel gears 24 which mesh with the bevel ears 25 to drive the parallel shafts 26 and 2 in opposite directions. On these shafts 26 and 27 are 'Secured the sprocket wheels 28, which drive the wheels 8 and the mandrels 11 by means of the chains 30. The pulley 29 drives the shaft 23. Secured on this main shaft 23 are other bevel pinions 31 which engage the bevel gears 32 on the shafts 33. These shafts carry the sprocket wheels 34 on which the chains 35 run, which chains also engage wheels 36 on the shafts 37, which shafts also carry the 'drums 38. Rings 39 properly spaced and positioned on these drums 38 form the cams for actuating the levers 19,

throulgh the small rollers carried on the pins 40. or each cycle of the machine,that is, at the forming of a tube, the shafts 37 make one revolution, and each mandrel makes a sufiicient number of revolutions to wind a tube while the other is discharging, and makes an equal number of revolutions while the other is winding, in the mean time sllding to the right Fig. 10) until the tube 1s discharged and t en-returning to original position.

The heavy roll of paper- 42 is mounted on.

the shaft 46 which is guided at the rear of the machine by the guide bars whlch are ivoted at 44 and held in position by the Its 45. The end of the machine isprovided with a vertical flange 47 which also serves to guide the shaft 46. See Flg. 3. The roll of paper rests on the constantly running roll 48 which is driven by the sprocket wheel 49. See Fig. 4. A 'chaln 50 connectsto this sprocket wheel and to a sprocket wheel of proper size on the shaft 27. The speed of the roll 48 is such, that tube matenal will be unwound at the same rate that the mandrels wind the same.

Vertically extending from the plate 1 are two frames 50 which carry rolls 51 and 52 at the upper ends. These rolls are held together by springs 53 which force the bearlngs of the roll 52 toward the roll 51. See Fig. 12. The rolls are driven by means of the s rocket wheel 55, the chain 56, and sproc et wheels 57 on the shaft 27, and the surface speed of these r'olls is constaht and equal to that of the mandrel.

Mounted in the frames 50 are shear rolls 59 and 60 as shown in Fig. 8, which "are connected by means of the small gears 61 shown in Fi 3. At the opposite end of one of the rol shafts from the gears 61 is a sprocket wheel 62 connected directly to the shaft of the roll 59. A chain 63 is driven by a sprocket wheel 64 on the shaft 65, which shaft is given a full revolution at each revolution of the shaft 33 by the intermittent gearing shown in Fig. 13. These shear rolls make one revolution for each tube, that is, two revolutions at each cycle of the machine, the cycle of the machine bein the operations during the formin of a tu e on onemandrel. A shaft 66 is riven by means of a chain 67 which passes around the wheel 68 on this shaft, and around a smaller wheel 69 on the shaft 33. See Fig. 8. 1

After the material has been sheared by means of the rolls 59 and 60, a new portion feeds down between the pairs of rolls 71, 72, 73 and 74 that are carried by the penduthe .1

lum-like frame 74. These rolls guide the tube material, but are not in such close adjustment as to prevent the material being pulled from between them at more than their surface speed. This frame is hun on the pivots 75 between the frames 50, an

to its lower end is connected a link 76 which also connects to the upper end of the lever 77. (Fig. 8.) This lever carries a in 78 which is adapted to travel in the cam oove 79 in the disk 80. This cam groove 1s formed of four parts, two rests of 90 degrees each and two actuating ortions of the same angulari The disk -1s mounted on the shaft 66 whlch makes one revolution shaft 86 of one roll 71 meshes with the ear 84 and the second roll 71 is driven by 'ction from the first. On the shaft 86 is a sprocket wheel 87 which connects by chain to another sprocket wheel on one roll 72. This roll in turn drives a roll 73 by means of chain gearing as shown in Fig. 5, and rolls 74 are in turn driven by the rolls 73. The chain 88 passes around the wheel 82 and the wheel 89 on the shaft 26. Between the rolls 71, 7 2, 73 and 7 4, the. tube material is guided by the plates 90. The sleeve 83 forms a bearing for one pivot pin 75. Spring held. rolls 91, Figs. 2 and 8, force the tube material toward the mandrels. These rolls contact. with the mandrels and are driven thereby.

To coat thetube material with glue or other cement, any desirable mechanism may be employed. That shown in the drawings is a pair of rectangular boxes 93 having freely revolving rolls 94 in their bottoms, which rolls are adapted to turn when they contact with the mandrels. As it is desirable that these rolls should not smear glue on the mandrel direct, and to leave the outside of the tube clean, means are provided to move the glue receptacles in and out from the mandrels. The receptacles 93 have flanges 95 that rest on the plates 96 carried by the side frames 97. Arms 98 (Fig. 3) project out-ward and carry pins 99 that engage grooves 100 in the drums 101. These drums are driven by the chains 102 which run on the wheels 103 on thedrums and'104 on the shafts 105. Chains, 106 running on the wheels 107 on the shafts and 108 on the shaft 23, drive the shafts .05 and drums 101, one revolution at each 0 cle of the machine, moving the rollers 94 mto employed. If the machine is set so that the contact with the beginning of the'first wrap of paper on the mandrel and removi the same ust before the winding is comp eted. Formed transversely of th e'ca'sing and be neath the frames 50 is a trough 110, in the bottom of which is a belt 111 which runs on pulleys 112. A sprocket chain 113 running Figs. 1, 2, and 3, sothat the roll of paper.

rests on the roller 48. The end of the tube material is then moved up and the end passed over and down between the rolls 51 and 52, between the shear rolls 59 and 60, and between the rolls 71, 72, 73 and 74 The end will then project down to the contact point between the mandrel l1 and the presser roll 91, the parts thus far described being the position shown in Fig- 8. The machinery is then started and through the action of the air pump a suction occurs through the holes 12 in the mandrel which will draw the paper against the mandrel, winding it up on the same. .As the paper is being wound one half of a wrap, the glue receptacle 93 is moved against the mandrel causing the outer surface of the paper to be coated. After the desired amount of paper has been wound and sufiicient further material to complete the tube extends from the mandrel to the shear rolls, these shear rolls will operate to sever the paper. The mechanism to operate these shears is simple, well known, and need not be again described.

Any other desirable shearing mechanism and driving mechanism for the same may be paper will be wrapped six times aroundthe mandrel ,to form a tube, the cam 80, the lever 77, and the link 7 6' will begin to operate at the end of the third wind and the.

'- of every six WlHdS; The result will be that the paper will pull out from between the pairs of rolls carried by this swinging frame faster than the-normal feed and the result will be that the next quantity of paper which is to be wound on the second mandrel will freely feed down between the rolls on this frame and reach the second mandrel in time to be gathered over the suction holes 12 and wound thereon. While the first three wraps of paper are wound on the'second mandrel the cam rings 39 on the drum 38' are the belt 111, and be conveyed-out ofv the machine. During the last three'winds of the tube on the second mandrel and while the frame 74 is swinging toward the first man drel, this mandrel is returned to winding osition through the'action of its lever 19,

and at the instant that the paper reachesit, the mandrel will be in position for winding the next tube. It will be understood, however, that these numbers ofwraps are only taken to illustrate the operation of the and the return to winding position may all be changed to suit requirements.

The object attained by longitudinal-1y grooving the mandrel is explained in the Harbeck Patent No. 869,902, dated Nov. 5th,

1907. The length of the mandrel will of course depend upon the material employed and upon the purposes for which the tubes are to be used. Usually these tubes will be employed for the manufacture of containers and each tube will be cut into proper lengths for such container bodies on special maehinesf The general design of the machine and the various details in construction may be changed to suit various conditions by those skilleo'in the art without departing from the spirit of my invention. Thus instead of the mandrels being longitudinally slidable, the construction shown in Patent No. 862,390 dated Aug. 6, 1907, to J. R. Harbeck may be installed to remove the finished tubes. Any other desirable form of gearing may be substituted for the chain gearing so long asit is positive in its action, belting being objectionable because of its tendency to slip.
